Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment, in particular to a polymer turnover box injection molding device. Background Art

[0002] Turnover boxes, also known as logistics boxes, are widely used in machinery, automobiles, home appliances, light industry, electronics and other industries. They are acid-resistant, alkali-resistant, oil-resistant, non-toxic and odorless. They can be used to hold food, etc. They are easy to clean, have convenient parts turnover, are neatly stacked, and are easy to manage. In the production process of electric bicycle lithium batteries, turnover boxes are needed for the transportation, distribution, storage, circulation and processing of lithium batteries.

[0003] The Chinese utility model patent with application number 202220113401.8 discloses a plastic turnover box injection extrusion device. In the above technical scheme, the second motor drives the moving module to slide along the slide rod and disengage from the fixed module to realize the unloading of the turnover box. At the same time, the second motor drives the rotating shaft to rotate through the belt assembly, so that the second screw drives the slide plate and the U-shaped plate to slide along the convex slide groove, so that the rectangular block moves into the rectangular groove to prevent the hot-melt material in the conical cylinder from being dragged.

[0004] In the above technical solution, after the product is cooled and formed, the demolding mechanism directly drives the polymer turnover box to demold, and it is difficult to detect the demolded products in time. When subsequent tests find that the amount of polymer material injected is insufficient, many unqualified turnover boxes have been produced, which in turn affects the economic benefits of the factory. At the same time, if the demolding is not thorough, there will be material remaining inside the mold. The above technical solution is also difficult to detect problems in time, which will cause waste of raw materials and reduce the qualified rate of products.

[0026] like Figure 1-5 As shown, a polymer turnover box injection molding device includes a bottom plate 1, a first mounting plate 2 and a second mounting plate 3 are arranged at the top of the bottom plate 1, a sliding plate 4 is slidably arranged between the first mounting plate 2 and the second mounting plate 3, a moving module 401 is arranged on one side of the sliding plate 4, a third mounting plate 7 is arranged at the top of the bottom plate 1, a fixed module 701 is arranged on one side of the third mounting plate 7, a demoulding member 5 for ejecting the polymer turnover box is arranged on the sliding plate 4, a distance meter 6 is arranged on one side of the sliding plate 4, and a shock-absorbing weighing device for shock-absorbing and weighing the demoulded polymer turnover box is arranged on the bottom plate 1. Component 9, the shock-absorbing weighing component 9 includes a support plate 903 slidably arranged on the top of the bottom plate 1, a pressure sensor 907 is arranged on the top of the support plate 903, and a controller 10 and a buzzing alarm 11 are arranged on one side of the third mounting plate 7; specifically, the rangefinder 6, the pressure sensor 907 and the buzzing alarm 11 are all electrically connected to the controller 10, which are all prior arts, so the principle, structure and model thereof are not described in detail here. When the polymer turnover box is injection molded, the driving component 8 is arranged to drive the moving module 401 to move in the direction of the fixed module 701. After the injection molding is cooled, the moving module 401 is away from the fixed module 701, so that the polymer turnover box is separated from the fixed module 701. The set distance meter 6 can measure its position to the first mounting plate 2. When the moving module 401 is moved to the position set by the distance meter 6, the driving component 8 will be controlled to stop working, so that the moving module 401 can move to the position above the support plate 903. The demoulding component 5 set later can push the finished polymer turnover box inside the moving module 401 outward to realize the automatic demoulding of the product. After demoulding, the product will fall above the support plate 903. Under the action of the shock-absorbing weighing component 9, it can play a buffering role on the product to prevent it from being damaged by bumps. At the same time, the pressure sensor 907 can measure the weight of the product after the spring 905 is stable. If the value measured by the pressure sensor 907 reaches the set value range, it means that the product is qualified. Otherwise, it means that the injection volume of the polymer material is too low, or part of the turnover box remains inside the mold, which means that the product is unqualified. At this time, the buzzing alarm 11 sounds, reminding the staff to check the problem of the mold device to avoid affecting the quality of the product and ensure the economic benefits of the factory.

[0027] like Figure 5 As shown, the second mounting plate 3 is provided with a making way groove 301 for making way for the movable module 401; specifically, the setting of the making way groove 301 will not block the movable module 401, and thus will not hinder the mold closing.

[0028] like Figure 2 As shown, a driving component 8 for driving the sliding plate 4 to slide is arranged between the first mounting plate 2 and the second mounting plate 3, and the driving component 8 includes a motor 801 arranged on one side of the first mounting plate 2 and a screw rod 802 and a slide rod 803 arranged between the first mounting plate 2 and the second mounting plate 3. The screw rod 802 is connected to the main shaft end of the motor 801, and the sliding plate 4 is threadedly sleeved on the screw rod 802, and the sliding plate 4 is slidably sleeved on the slide rod 803; specifically, the motor 801 can drive the screw rod 802 to rotate when it works, and then drive the sliding plate 4 to slide, so as to drive the moving module 401 to slide and close the mold.

[0029] like Figure 4 As shown, a through hole 4011 is provided between the sliding plate 4 and the moving module 401 for penetrating connection.

[0030] like Figure 4 As shown, the demolding member 5 includes an electric telescopic rod 501 arranged on one side of the sliding plate 4 and a push rod 502 slidably arranged inside the through hole 4011, and the push rod 502 is connected to the telescopic end of the electric telescopic rod 501; specifically, after the moving module 401 is moved above the support plate 903, the electric telescopic rod 501 can push the push rod 502 to move, and the movement of the push rod 502 can eject the polymer turnover box product inside the moving module 401 out of the mold.

[0031] like Figure 2 As shown, a fixed plate 901 is provided at the top of the bottom plate 1, and a limiting telescopic rod 902 is respectively provided at the four corners of the top of the fixed plate 901, and a supporting telescopic rod 904 is provided in the middle of the top of the fixed plate 901, and a spring 905 is sleeved on the supporting telescopic rod 904, and the supporting plate 903 is connected to the telescopic ends of the limiting telescopic rod 902 and the supporting telescopic rod 904, and a baffle plate 906 is provided at the top of the supporting plate 903; specifically, the supporting telescopic rod 904 and the spring 905 provided can play a shock-absorbing role for the fallen products to prevent them from being damaged and deformed, and at the same time, the limiting telescopic rod 902 provided can limit the support plate 903, so that it can ensure movement in the up and down directions, and can prevent the support plate 903 from being skewed, and at the same time, the baffle plate 906 can also prevent the cooled polymer turnover box products from falling, and the area of ​​the support plate 903 is larger than the area of ​​the polymer turnover box products, so as to prevent them from falling to the surface of the support plate 903.

[0032] In summary: when the polymer turnover box is injection molded, the driving component 8 is set to drive the moving module 401 to move in the direction of the fixed module 701. After the injection molding is cooled, the moving module 401 is away from the fixed module 701, so that the polymer turnover box is separated from the fixed module 701. The set rangefinder 6 can measure its position to the first mounting plate 2. When the moving module 401 is moved to the position set by the rangefinder 6, the driving component 8 will be controlled to stop working, so that the moving module 401 can move to the position above the support plate 903. The demoulding component 5 set thereafter can eject the finished polymer turnover box inside the moving module 401 outward, so as to achieve the product Automatic demoulding. After demoulding, the product will fall onto the support plate 903. Under the action of the shock-absorbing weighing component 9, it can buffer the product and prevent it from being damaged by bumps. At the same time, the pressure sensor 907 can measure the weight of the product after the spring 905 is stable. If the value measured by the pressure sensor 907 reaches the set value range, it means that the product is qualified. Otherwise, it means that the injection volume of the polymer material is too low, or part of the turnover box remains in the mold, which means that the product is unqualified. At this time, the buzzing alarm 11 sounds, reminding the staff to check the problem of the mold device to avoid affecting the quality of the product and ensure the economic benefits of the factory.
